FIELD: methods for placing of free-flowing of explosives in hoses in steeply inclined dry and flooded holes.
SUBSTANCE: the method consists in assembling and attaching of the main hose by the open end on the hollow guide and attaching of the additional hose made of nonhermetic high-strength material on the mentioned hollow guide. The main hose is placed in it with provision of simultaneous coming-off of them. The device for placing of the explosive in the hose in a descending hole has a hollow guide with the main hose assembled in a pack and attached for coming-off, with a closed end and braking means. The device has a charging component installed over the hollow guide, the braking means is positioned in the upper part of the hollow guide, on which the additional hose is assembled in a pack, and it envelops the main hose made of nonhermetic high-strength material. One end of the additional hose is passed through the braking device and attached at the charging component, and the other end is closed.
EFFECT: enhanced reliability of placing of the charge in the hole.
